New(ish) Vitamin D Research

I'm sure we all know Vitamin D is important here, but I ran across this research this morning and figured I'd pass it on!

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5541280/

From the conclusion:

"Unfortunately, medicine took a very long time to realize that vitamin D is not simply a vitamin that prevents rickets. For that purpose, 400-600 IU/d may be enough. However, we know today that vitamin D is a powerful nuclear receptor-activating hormone of critical importance, especially to the immune system. With the available data mentioned above, the proposed doses would probably suffice to maintain vitamin D levels around or over 75-100 nmol/L, with practically zero risk of toxicity. Undeniably, further studies are needed to clarify the optimal supplementation of vitamin D, although it is uncertain whether a universal recommended dietary allowance is feasible. Meanwhile, actions are urgently needed to protect the global population from the threats posed by vitamin D deficiency."

Great reminder! This is the only vitamin that came back low for me a few months ago. Fingers crossed it's higher when I get it checked again in a month!
